摘　　要：卧式埋弧焊机高速焊接使用的焊丝和焊剂进行国产化替代,并在此基础上使用气保焊焊丝代替埋弧焊焊丝进行焊接,获得了成功。通过实践、理化试验相关金相证明,该焊接新工艺是可靠的。探索出的一条适合该卧式高速焊接的焊接工艺即ER50-6+SJ101的焊接新工艺,与旧工艺相比,新工艺应用广泛、取材广,应用价值和经济性更好。新工艺已经成熟,焊接质量稳定,焊接速度满足生产要求,焊接成本也大幅度下降,经济效益可观。This paper intrnduced high level domestic manufactured wires and fluxes for high speed submerged arc welding machine,and based on the using gas shielded welding wire instead of submerged arc welding wire, had finally achieved success. And through practice, physical and chemical test metallographic proves that the new welding process is reliable. Explore a suitable for the division of high level high speed welding technology namely ER50- 6 ＋ SJIOI new welding process compared with the old technology, new technology, wide materials used widely, and its application value and economy better. Now new technology is mature, stable welding quality, welding speed meet the production requirement, the welding cost, a big drop in value has been made on the very considerable economic benefits.
